Abstract

1310289 Helical gear pump or motor SHIMADZU SEISAKUSHO Ltd 18 June 1970 [18 Nov 19691 29698/70 Heading F1F In a gear pump or motor in which the gears 11, 12 have helical teeth, the axial thrusts A and B on the gear shafts 21, 25 are balanced by supplying liquid from the high pressure side of the pump or motor to suitably dimensioned chambers 57, 58 in an end plate 16 to act on the ends of the shafts. The liquid may act on the ends of the shafts through plates 53, 54 piston-like members 5], 52 having ring seals effecting sealing of the chambers 57, 58. The gears 11 12 are sealed axially by pressure-loaded check-plates 34, 35, the relative effective areas of which, as defined by seals 40, 41 are such as to produce an axial force on the gears 11, 12 and shafts 21, 25 which respectively supplements and counteracts the axial forces on shafts 21 and 25 due to the helicity of the gears, the net effect being the unequal thrusts A and B.
